Feasibility Studies of an Electrochemical Test Method for Nitrogen Tetroxide Compatibility Testing.
Abstract
The application of the electrochemical compatibility test method to metals exposed to nitrogen tetroxide (N2O4) is described. It was determined that N N2O4 is not sufficiently conductive to permit electrochemical measurements to be carried out. It was necessary to add water in the concentration range of ten to eleven value percent in order to obtain compatibility data. This concentration corresponds to the high density acid phase of the N2O4 - H2O system. Above one to two value percent water a small portion of the high density acid phase is formed which can produce localized corrosion. It is suggested that corrosion in the high acid phase should be considered for further study even though the overall water concentration is quite low. (Author)
